What is Edge Computing?
Running code at network edge locations geographically close to users for minimal latency.
Definition
Edge computing processes data at the edge of the network, close to where it's generated or consumed. In web development, edge functions (Vercel Edge Functions, Cloudflare Workers, Deno Deploy) run at CDN edge locations worldwide, providing sub-millisecond cold starts and single-digit millisecond latency. Use cases include personalization, A/B testing, geolocation, authentication, and API proxying.
